The present disclosure provides a cylindrical structure construction platform that both a first telescopic portion and an elastic member drive a guiding wheel to tightly abut against an outer template, adjusting radial positions of a pouring pipe and a tamping device according to an outline of the outer template by a second telescopic portion to reduce construction errors, adjusting an inclination angle of the guiding wheel by an adjusting mechanism, a slewing mechanism driving a rotary table to drive the guiding wheel to climb along a surface of the outer template, the pouring pipe is poured layer by layer from the bottom to the top of a pouring cavity to reduce a height difference during pouring for further reducing generation of air holes, the tamping device vibrates layer by layer from the bottom to the top of the pouring cavity to further eliminate the air holes.

Cylindrical structure construction platform

A construction platform that is freely movable up and down is provided, which includes several curved platforms, several columns and a control panel. The curved platforms are connected with one after the other to form a ring-shaped platform that surrounds a cylindrical building and is movable along the columns. Each curved platform is provided with one or more mounting brackets. Each mounting bracket is provided with one or more movable brackets, one or more pressing mechanisms, one or more locking mechanisms, one or more movable rods, one or more suction cups, a pumping mechanism, and one or more emergency braking mechanisms. Each emergency braking mechanism includes a sprocket, a chain, a counterweight, an angle sensor, and a configuring assembly. Each configuring assembly includes a ring gear, a mounting sleeve, a configuring rod, a pawl, a torsion spring, an electromagnet and a magnetic block.

Freely movable construction platform

A recyclable pile foundation is provided. The recyclable pile foundation includes several inner cylinders, several outer cylinders and several reciprocating components which are circumferentially distributed between the inner cylinders and the outer cylinders. Each reciprocating component includes several steel collars, a push-pull rod, a hold component and at least one motion component. The motion components are distributed along the push-pull rod. Each motion component includes at least one triangular connection plate, several connection rods, an inner wedge block, an outer wedge block, a motion block and a pointed rod. When the push-pull rod is pushed along its own axis to the pushed position, the pointed rod protrudes from the outer cylinders to increases the friction between the surrounding soil and the recyclable pile foundation. When the push-poll rod is pulled along its own axis to the pulled position, the pointed rods retract back into the outer cylinders.
